To aliwhomlz't may concern:

Be it known that I, HAROLD MGD. BROWN, a citizen of the United States, and resident of`Groton, in the county of Tompkins and State of New York, have invented certain new: and .useful Improvements in Type writing Machines (Case 184), of which the following is a specilication. Y

This invention relates to improvements in typewriting machines, and more particularly to paper feeding means lfor such machines.

The invention has for its principal objects to provide simple and eilicient mans' for supporting and guiding a continuous strip orl web of paper on the traveling platen carriage ofV a typewriting machine so that the web Ymay be led from a vsupply roll to the printing point; to. provide means for supporting a` roll of paperor a plurality of rolls of paper ofthe same-or different widths, on-the platen carriage in such manner that either or all of the rolled strips of paper may be fed to the printing point;

to provide a roll-holder for perforated label strips or other rolled Webs of paper of light weight and inexpensive construction; toV provide simplev means for detachably supporting a roll holder on the. platen c-arf` riage to travel with the carriage; to pro.g vide meansfor preventing accidental spin ning or unrollingof the web or webs of paper mountedin the holder; to pro-vide La roll'holder and supporting m'ans' theref for Vso constructed that the holder may be securely mounted on the carriage without employing separate fastening or clamping devices and that the roll or lweb. may be mountedin the holder without employing .inuts,' screws or the vlike to Vretain theroll supportingrod or shaft in place;` and 'to Vprovide a detachable roll supporting means Vvlso constructed and arranged as not to inters ferewith the ordinary use of the machine for writingi'upon sheets when the roll supporting means is attached tothe machine.

,To the foregoing and other ends, which `vwill hereinafter ap,pear,vthe` invention con-k zsists inthe improved construction of def-vic"s, the' arrangements of parts, and combinationsof elements, set forth in the following description and particularly pointed "out in the appended claims.

Thelimprovev ents are illustrated in connection with the Corona typewriting inachine, a well known machine of' the frontstrke type a 4platen carriage fed-step byY step for letter-spacing, vand aplatenfsupported on the carriage and rotatable for spacing between lints of-writing. It will be obvious, however, thatA the 'improvements may be employed with other typewriting machines.

In the. accompanying drawings, wherein is illustrated one satisfactoryA andV desirable embodiment Vof the invention, andin which similar reference characters designate corresponding Vparts throughout the several views:

Referring to the drawings by numerals, 1` designates the platen of a Corona type writing machine, 2 the platen carr .ge which is fed stepby step transversely of the machine during writing, 3 the paper table or apron mounted on the carriage, l the'l paper feed roller which is rotatably mounted on the forward edge of thepapertable, 5 the scale bar Awhich is held to the papertable forwardof the feed roller, and 6 the main frame of the machine .in which the type-bar action is mounted. The foregoing` Vpart-s are'all of the usual construction.

Two sheetk metal brackets 7 are rigidly secured at 8, by spot welding or otherwise,

to; the rear. face ofthe paper table 3 Vadjacent the'upper edge of the table and near oppo- .site ends of said table.l The inner ends of the brackets are offset from the rearface of the paper table, as shown more clearly in Figs. 6 and 10, and two sheet metal bars i Qfarepi'votally" held to: the inner offset ends of said brackets by screws 10. Bars 9 are preferably tapered from their pivots toward ltheir free ends. As shown, the inner edges of` the bars incline toward the outerVV edges of the bars from the hinged ends of the bars to the free ends thereof, while the outer edges of the bars are parallel. with the longitudinal center lines of `the fbars, lout both side edges of eac-h bar may be inc-lined toward the longitudinal center line of the bar if desired. r

Screws 10 extend loosely through apertures l1 Vin bars 9 a short "distance from the lower ends of the bars to provide short armsl2L adapted toengage stop lugs 12 on the vbrackets 7 to arrest the bars V'in overlap ped horizontal position under the paper table when the bars are swung inwardly and downwardly to compacted noiruse position. as Ashown in Fig. 12. llnigs 12 also coact with the rlonger arms of bars 9, Vas shown in Figs and 6, to limit the upward andV outward swingingimovements of 'the bars, said stop lugs arresting the bars when they reach a slightly laterally di'vergl position` as shown in Fig. 3. 'Bars'.(l 'form paper or label roll holdingframe. Y

VThe roll-holding frame is vpreferably stamped" 4from a 'single -rectangular sheet metal blank and, asshown, comprises longitudinal cross-bars .13 and 14 and integral endbars 15v and 16. The rear cross-bar is form'ed Vwith an npstanding flange 17 VValong itsrear edge, and 'thefffront erossfbar .Metis formedV with*` an upwardly and for- Vw'alrclly rolled ange '1'8 along its rear edge and two'V upstanding lugs or short flanges 19 at each end of the forwardv edge thereof.

avoiding the expense of supplying a specialr metal or other shaft with theroll-support ing` attachment, but it willbe Vobvious that any suitable shaft may-be employed.

The flange 17 is provided adjacent its ends with two slots 24 in register with slots formed in the short flanges or lugs 19 on cross-bar 14. rlhe slots 24 and 2li arel sufficiently wide to receive the arms 9 and are as long as or longer Ythan the Vgreatest width of said arms at least up to a point adjacent the apertures 11 in the arms.

To connect the frame to the paper table, the arms 9 are swung outwardY and upward until their longitudinal renter lines are at right angles to a line through their pivots. The two slots 24 and the two slots 25 are spaced apart longitudinally of the frame av distance. equal to the distance between the inner edgesY of the .outer ends ofl arms 9 when in this position so that the frame may be slipped on the outer ends of the arms as shown in Fig. 10. They inclination of the inner cam edges. (if-'the arms 9 is such, howerer, that as the frame is moved farther dowi'iward and forward on the arms, the arms will be cammed outward by the Venfil) gagement of the inner ends'of slots 25' with the inclined inner edges of the arms until the outward `movement ofthe arms is arrested by stops 12, as shown in Fig. The parts are preferably so proportioned that at this time the outer edges of arms 9. will abut against the outer enjds of slots 24?, as shown more clearly infFig. 111. y .isla-rms .Q'are arrested atuniform angles to theaxis of the platen, by stops the frame. and the axial line `of bearing` apertures 22 in arms 20 the-reim w'll be parallel Vwith the axis of the platen and a roll or rolls of paper on shaft 23 will'be parallel withfthe platen.

To mount aroll of paper, blank paper labels, or'the'like, inthe frame, the pencil or other shaft Yor rod 23 is passed through the tubular core or spool 26V upon which the paper web or strip-27 'is wound andV also through the bearings on apertures 22y in arms 20. -The rolled web orpaper strip shownconsists of'a strip of paper printed and perforated transversely to form a series .of blank labels. YIt will be obvious that the bent" portionor head 29. atl a? right angle tothe dependingfmain armr portion thereof.

AHead 29 is formed withan integralfrear- :Arm l28 is attached to the cross-bar 1 3 of the frame by engaginghool's 3l over flange 17` adjacent the endfbar 15 of the frame'as shown in Fig. 4, then rocking said arm forwardlyto' `pass hook` 30 through a notch 33 in the forward edge of bar13, and then sliding said arm laterally along the bar. Arm 28 -is' provided adjacent its lowerend with a shaft bearing ori aperture 34fnormally out of register, or axial alignment with the apertures 22 in ar1ns20', asA shown in Figs. 7 and 10, b ut adapted to be moved into register With the apertiifres 22.

`Spring t`o`ngue-32 normally holds thefupper face of head 29 spaced from bar 13Ya`n1d holds, the upper ends of'hooks" 30V and 31 against the upper face of bar 13 and the 'upper edge of flange 17, respectively, as

shown in Figs'.V 5 and 7 when shaft' 23 is removed. To mount a label; roll, and a 'sn'pporting shaft therefor, in the framel arm 28 is pressed forwardly, cempres'sing the spring tongue 32 and causing head 29 to rock slightly vrelatively to bar 13 ,as shown inv Fig. 6 until aperture 34registers with apertures 22, whereupon shaft 23 is passed lthrough the bearing apertures `in arms 20 and 28' and throughv cio're` 26 of the labelroll.

` Core 26 preferably nts loosely onfthe shaft rpencil 23 assho'wn in Fig; 8,so` as tov Vrevolve freely thereon, and the rodlorpencil preferably fits snugly i1i"its'b'e`aring` apertures l22- and 34. .p

As arm 28`t`ends to spring back to its normal position, itl exerts transverse" pressure @a Shaft 2e and time 'fiiciioiiiauy holds the shaft 'against Vaceidental Vendwise displacenient and also against rotationfinits bearings or supportingape'rtures. Arm 28 and arms 20 are formed-of thin and inherently resilient sheet iiieiai` and are therefer'e 'iat erally flexible.y Thisv assists in preventing aceidental endwise movement of the shaft assu'ch movement, owing to frietin in the bearing apertures', tends to flex thearms laterally and thus causes'a oramping action ofthe arms on the sha-ft 23.y 1 i l Spring tongue 32 also serves "te frietion- Vally hold the arm" 28 in adjusted position onbar13, and said arm ispr'eferably ad j iist'ed longitudinally ofbai is tefiigiitiy clamp the label roll ,27 between said armf andv thearm` 20 which depends freinA iframe Y barflty ELSShwn in'Fig. 3; The label roll is thus fricti'onally held again'stfaecidental iiiirollingas weil. as against a ton free rotary movementv when the web 27 is" fed threngh the paper feed devicesofthe machine; Web 27 isled frein the roll over the rounded guide flange '18 on the roll-holding frame to the paper table 3, and is fed around the platen to the printing point by the usual paper feed mechanism and line space mechanism ofthe machine. Y

W'hen AtwoV or more rolls of labels' are mounted on shaft23, one or'mo're' additional detachable arms 28 are employed, the additional roll or rolls being each clamped bet/Ween two `of the arms 28, as indicated in dotted lines in Figf, so that the several webs may be fed in unison'or independently 'to the printing point.
